im wf/- EIlm UNITED IMPROVEMENT IN CAR-WHEELS.

Specification forming part of Letters Patent No. 122,661, dated January 9, 1872 antedated December 23,1871.

To all whom it may concern:

Be it known that we, JOHN C. RUPP and STEPHEN OTT, of Newark, in the county of New Castle and State of Delaware, have iuvented new and useful Improvements in Car- Wheels; and we do hereby declare the following to be a clear and exact description of the nature thereof, sufficient to enable others skilled in the art to which our invention appertains to fully understand and use the same, reference being had to the accompanying drawing making part of this specification, in which- Figure 1 is an end view of the device illus trating our invention. Fig. 2 is a central vertical longitudinal section thereof. Fig. 3 is a top view of one of the boxes. Fig. 4 is a liront View thereof.

Similar letters of reference indicate corresponding parts in the several figures.

Our invention relates to an improvement in car-wheels.; and consists of wheels which turn freely on the axles, and also bear and turn on blocks which are fixed to the axle, so that the internal bearing-surfaces of the wheels are greatly increased, the wheels moving' simultaneously on the axle and boxes. The wheels will readily rotate in turning curves, so that the usual objections to fixed wheels are overcome. The boxes' are also designed to receive the weights of the car-trucks, and likewise form oil-chambers for lubricating the journals.

In the drawing, A represents an axle, which may be of any well-known form and construction. B represents the wheel proper. It cou sists of the usual flange and body, and has an opening, through which passes loosely the axle, so that the wheel may freely rotate thereon. 0n the faces of the wheelwe form swells or enlargements C, which leave shoulders D, as readily seen in Fig. 2. On the axle A, on both sides of the wheel, there are arranged boxes E E, which are keyed, bolted, or otherwise secured to the axle. These boxes have shouldered portions F, which project into the spaces circumscribed by the shoulders D of the wheel, and the shoulders D F have a bear ing in each other.

The inner faces of the vmain portions E of the boxes bear against the faces of the wheel at or about the enlargement C, so that when the wheel is in operation it rotates on the axle A and the shouldered portions F of the blocks, whereby there is an enlarged bearingsurface, and the wheel is permitted to rotate uniformly and lirmly without rattling, while lateral displacement is prevented by the main portions E of the blocks, which embrace and coniine the wheel in place.

The tops of the blocks are constructed to form bases or rests for the hangers or framework of the trucks of the car, and they likewise constitute the means for lubricating the journals without additional appliances for that purpose. To this end passages al a are made in the boxes, which extend to the openings through which the axle passes, so that the lubricating material is readily conducted to the journals.

Besides the utility of the invention, as here tefore described, we are enabled to use a light axle, since the boxes increase the inner bearings of the wheel, and thus render a heavy axle unnecessary. The boxes also prevent lateral movement of the wheel, and likewise provide the means for conveying the lubricating material to the axle or journals.

The portion of the axle which carries the boxes may be round or angular, as most desired, and the openings in the said boxes must be of corresponding form. The inner faces of these openings may be screw-threaded to iit -over similar threads on the portion of the nation with the fixed boxes E, having shoulsubstantially as and for the/purpose described. dered portions F, which project into the spaces The above signed by us this. 29th day of formed by the shoulders D and the main por- April, 1871. tions E, which embrace the sides of the wheel, JOHN C.
